Which of the following reactions involve oxidation reduction?

Answer»

`2Rb +2H_(2) O rarr 2RbOH+H_2`
`CuI_2+Cl_2 rarr CuCl_2 +I_2`
`NH_4 Cl +NaOH rarr NaCl +NH_3 +H_2O`
`4KCN +Fe (CN)_2 rarr K_4[Fe(CN)_6]`

Solution :Reactioninvolve OXIDATION reduction . (a) `2overset(0)(Rb)+2overset(+1)(H_2)Orarr2overset(+1)(Rb)OH+overset(0)(H_2)`and (b) `2overset(+2)(CU)overset(-1)(I_2)rarr2overset(+1)(CuI)+overset(0)(I_2)`INVOLVE oxidation reduction.
